Right, the "The Requirements for Japanese Text Layout" is a fantastic
description of the rules of Japanese layout. But it's clear to me
that vertical text layout isn't a simple *addition* to CSS, it's a
reworking of CSS; very basic properties need to be rethought,
adjusted, tweaked, etc.
That's why I think it's important to try and understand the full scope
of how vertical text affects CSS, to simply list existing properties
and how they might be affected. Doesn't need to be a PhD thesis, just
a simple methodical analysis that covers CSS 2.1 and additions
proposed for CSS3.
